  • Patent number: 11152635
    Abstract: According to the invention, a method for parallel condensation and evaporation is provided for a fuel cell system with a condensation/evaporation device. In this case, the condensation-evaporation device (KVV) has a condensation chamber and an evaporation chamber, which are thermally coupled to one another via a heat exchanger so that water vapor contained in the condensation chamber in exhaust gas of a fuel cell stack is condensed into water and in the evaporation chamber a liquid fuel of a two-phase mixture comprising the liquid fuel and a gas phase, are at least partially vaporized to fuel vapor. In this case, the energy required for evaporation is at least partially provided by waste heat from an exhaust gas of a fuel cell stack of a fuel cell and the associated energy withdrawal from the exhaust gas of a fuel cell stack is used for condensation. The present invention is characterized in that the gas phase comprises a carrier gas which is CO2.

  • Publication number: 20170092968
    Abstract: According to the invention, a device is provided for extending the service life of a high-temperature polymer electrolyte membrane fuel cell. This device includes an HT-PEM fuel cell with at least one cell. The cell is constructed according to the following sequence: a supply plate with an anode channel structure, an anode gas diffusion electrode, an electrolyte-containing polymer membrane, a cathode gas diffusion electrode, and a supply plate with a cathode channel structure. In addition, at least one acid-filled acid reservoir is provided, which is connected to a distributor channel extending in the supply plates approximately perpendicular to the channel structures, the distributor channel being connected to at least one of the gas diffusion electrodes and/or the polymer membrane of at least one of the cells of the fuel cell stack in such a way that acid can be supplied to at least one of the gas diffusion electrodes and/or the polymer membrane of at least one of the cells of the fuel cell stack.

  • Patent number: 7572323
    Abstract: The invention relates to a fluid separating device with a lower section with a fluid feeding device and a liquid discharging device, an upper section with a fluid feeding device and a gas discharging device, a contact device which is constructed in such a manner that gas, which rises from the lower section into the upper section, comes into contact with liquid which sinks from the upper section into the lower section. Thereby, the rising gases can be depleted of components which are soluble in said liquid. Furthermore, a measuring device for determining the quantity of liquid and/or the alterations thereof is provided.

  • Publication number: 20070105009
    Abstract: The invention relates to a method and a device for monitoring the fuel supply of a fuel cell system and for protecting said fuel cell system against damage or destruction, if no fuel or insufficient fuel is supplied to the fuel cell system. If the flow of fuel is insufficient for supplying fuel to the fuel cell system or if the fuel reserve falls below a predetermined value, a signal will be output.

  • Publication number: 20060286415
    Abstract: The invention relates to a method for controlling the fluid balance in an anode circuit of a fuel cell system. In this method, at least the gases discharged on the cathode side are cooled in a condensing device in order to obtain a condensed liquid, and the condensed liquid is fed to the anode circuit of the fuel cell system. It further relates to a fuel cell system designed according to the principles of the inventive method.
